Keeping me guessing

Colette throws her food on the floor.
Then she asks to get down out of her highchair.
Then she tries to eat the food from the floor. And gets upset when I won't let her.
What is the attraction, I wonder?

Also of note:

When the doorbell rings, and the dog doesn't start barking wildly, it's a good guess that the person at the door is returning our dog.

It's also time to put a chain bolt on the door, out of Tiernan's reach.
